ABSTRACT:
An analog-to-digital converter includes a plurality of digital-to-analog converting circuits, a control circuit connected to the digital-to-analog converting circuits to control the condition of the respective digital-to-analog converting circuits, a comparator having a first input connected commonly to outputs of the digital-to-analog converting circuits and a second input connected to receive a reference voltage, and a successive approximation register connected to an output of the comparator and adapted to control the control circuit. The control circuit is adapted to generate control signals to the respective digital-to-analog converting circuits in one-to-one relation so that the output potentials of the digital-to-analog converting circuits are successively incremented one after one by a potential corresponding to one bit.
